IE: I cast Primal Surge and flip Garruk, Primal Hunter followed by Garruk Wildspeaker. Do I have to make the choice on putting Wildspeaker into play or do I wait for resolution of Primal Surge before I make the choice?
Wait a second here..
You have put the Planeswalker into play because if you don't, you don't repeat the process.. means you are finished with the spell
704.3. Whenever a player would get priority (see rule 116, "Timing and Priority"), the game checks for any of the listed conditions for state-based actions, then performs all applicable state-based actions simultaneously as a single event. If any state-based actions are performed as a result of a check, the check is repeated; otherwise all triggered abilities that are waiting to be put on the stack are put on the stack, then the check is repeated. Once no more state-based actions have been performed as the result of a check and no triggered abilities are waiting to be put on the stack, the appropriate player gets priority. This process also occurs during the cleanup step (see rule 514), except that if no state-based actions are performed as the result of the step's first check and no triggered abilities are waiting to be put on the stack, then no player gets priority and the step ends.
What is important here is that you check state based effect the next time a player gets priority (so when the spell is finished..), so you can choose to keep one Garruk and put the rest of them into the graveyard (im talking here about the planeswalker uniqueness rule..)
704.5j If a player controls two or more planeswalkers that share a planeswalker type, that player chooses one of them, and the rest are put into their owners' graveyards. This is called the "planeswalker uniqueness rule."
To reiterate; the decision to put either planeswalker onto the battlefield is made during the resolution of Primal Surge. After the spell is done resolving, you choose one of the Garruks to keep and one to send to the graveyard.

You make the choice when Primal Surge finishes resolving.

When in doubt, call a judge.
Objectivist here. Hit me up to talk philosophy.
